The Wheatstone development comprises the Wheatstone and Iago offshore gas fields. Production from these fields will be from subsea wells and manifolds, transported via insulated flowlines to the Wheatstone platform (WP) where the gas and condensate will be dehydrated and dewatered respectively and transported via a trunkline to the onshore LNG plant, located at Ashburton North, 12 km west of Onslow, on the Pilbara coast of mainland Western Australia.
